Question

我正在编译此代码并收到“输入时解析错误='``

的错误

import System.IO  
import Data.List.Split
main = do  
   handle <- openFile "ac/abc" ReadMode  
   contents <- hGetContents handle  
   let xs = splitOneOf "; \n " contents       
   print xs   
   readStrList contents = do 
       print contents
   hClose handle

请提出错误的建议

Answer 1

问题在于以下几点：

readStrList contents = do 
    print contents

如果您要定义readStrList，那么您需要将let放在前面：

let readStrList contents = do
        print contents

输入'='上的haskell错误解析错误
